Broiler Feed and Growth Chart

[Henlus]

Thank you. What if I feed starter from day 1 to 8 weeks and sell?  So that they grow faster.

Not a good idea at all. The nutrient requirements are not the same.

Finisher has more calcium content that will help build strong bones. Starter has more protein  which is good for growing chicks and bad for bigger chicks (liver damage).

And pls note that you should change from starter to finisher gradually by following the 75:25% rule. That is, on wk5 day 1 give 75% starter and 25% finisher. Wk 5 Day 2 give 50% starter and 50% finisher. Wk 5 day 3: 25% starter and 75% finisher. Finally on wk 5 day 4 give 100% finisher.
